I have a 03 Yamaha Warrior 350 and i am having problems with it now to where it will run great for about 10 minutes then it will shut off and not restart fro about 30 minutes. Can anyone give my some pointers on getting it back on the trail? I have put a new plug in, added a fuel filter, cleaned the air filter, had the valves checked, rebuilt the carb. I dont know what else i can do. Please help

 

Bad coil maybe?

 

Where is the best place to get one? I dont want to buy an expensive one and find out that is not the problem. Thanks raptorlegs

 

Unfortunately, when you wrench in the garage, its real easy to fix things that aren't broken. Nature of the beast. But try your local dealership. If not, I've had good experience with Rocky Mountain atv online.

 

Cool thanks. What do you think about bike bandit, or ebay? I found a performance cdi and rev limiter for 80.00 plus shipping would that be a good chance to take? I had a shadetree bike mechanic tell me it is the on off switch on the handlebar that the spring is losing tension. Does that sound like a possibility?

Thanks again

 

Since it seems like you're not sure where the problem lies I'd do some more testing before spending any money. I'd doubt it's the killswitch because if it were you should just be able to flick it off and on and then easily be able to restart your engine.

Check to make sure you're getting spark after it shuts off when cranking. If you don't then it's probably your coil.
